Object description (wikipedia.org):
The Elephant's Trunk nebula is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396 located in the constellation Cepheus about 2,400 light years away from Earth. The piece of the nebula shown here is the dark, dense globule IC 1396A; it is commonly called the Elephant's Trunk nebula because of its appearance at visible light wavelengths, where there is a dark patch with a bright, sinuous rim. The bright rim is the surface of the dense cloud that is being illuminated and ionized by a very bright, massive star (HD 206267) that is just to the west of IC 1396A. (In the Figure above, the massive star is just to the left of the edge of the image.) The entire IC 1396 region is ionized by the massive star, except for dense globules that can protect themselves from the star's harsh ultraviolet rays.
The Elephant's Trunk nebula is now thought to be a site of star formation, containing several very young (less than 100,000 yr) stars that were discovered in infrared images in 2003. Two older (but still young, a couple of million years, by the standards of stars, which live for billions of years) stars are present in a small, circular cavity in the head of the globule. Winds from these young stars may have emptied the cavity.
The combined action of the light from the massive star ionizing and compressing the rim of the cloud, and the wind from the young stars shifting gas from the center outward lead to very high compression in the Elephant's Trunk nebula. This pressure has triggered the current generation of protostars.

It was busy night taking photos of milky way's core. At the end of session tried to take some shots of Cassiopeia, to see if comet will be visible. What a nice surprise, it was visible, and beautiful as well.
Unmodified Pentax k-50, Skywatcher Star Adventurer tracker.
Nel 2010 ho comprato una SkyWatcher HEQ5 Pro usata. Era praticamente nuova ed usata pochissimo.
Durante i primi utilizzi mi resi conto che qualcosa non funzionava bene durante l'autoguida (a volte i frame presentavano le stelle allungate già con focali corte di 560mm). Ho fatto allora alcuni test per cercare di capire e risolvere il problema. Ho utilizzato per i test il riflettore SC C8 ridotto a 1650mm di focale e la Magzero MZ5m. Ebbene osservando il grafico AR con l'autoguida abilitata e disabilitata avevo capito che il problema non era software ma era dovuto alla montatura.
Infatti con l'autoguida disabilitata il grafico presentava oscillazioni in AR con continui massimi-minimi +3-4/-3-4 pixels che si ripetevano ogni 13-14 sec. Qualunque software per l'autoguida abilitata cercava di compensare questi errori ma spesso la correzzione si sommava alle oscillazioni provocando errori ancora peggiori. Andava un pò meglio impostando tempi di correzione uguali o inferiori ad 1 sec.
Qualcuno mi ha consigliato di revisionare la montatura: smontarla, pulirla e reingrassarla. Dopo quella fatica il problema è rimasto.
Poi osservando gli ingranaggi in movimento notai che il l'errore si ripeteva ogni volta che un dente l'ingranaggio del'albero motore entrava tra 2 denti dell'ingranaggio flottante centrale.
Ho cercato in tutti i modi possibili di ridurre questi errori agendo sulle distanze reciproche dei 3 ingranaggi, ma il risultato era pressochè uguale.
La possibile soluzione poteva essere sostituire gli ingranaggi con cinghie; nel frattempo avrei utilizzato il telescopio principale con focale inferiore a 500mm per non incorrere a mosso nelle foto a lunga posa.
Diverse aziende realizzano i kit di modifica con le cinghie, ma spesso la modifica comportava la perdita del rapporto di trasmissione originale rendendo inutilizzabile la pulsantiera della HEQ5. L'unico modo per gestire la montatura sarebbe stato utilizzare l'EQMOD.
Qualche mese fa ho saputo che la l'azienda Rowan Astronomy (UK) realizzava l'HEQ5 Pro Belt Modification Kit (www.rowanastronomy.com/productsa1.htm) che mantiene il rapporto di trasmissione della configurazione originale
Quindi ho comprato il kit. La modifica è stata molto semplice e in poco tempo.
Vi rimando all'album di Facebook www.facebook.com/media/set/?set=a.1199861523390411.107374... dove troverete altri dettagli e accorgimenti.
La prima cosa che si nota anzitutto è la drastica diminuzione del rumore metallico durante il go-to. www.youtube.com/watch?v=r5bu97zoRok , youtu.be/_WRNKh5xMFg
I grafici prima-dopo sono eloquenti. Adesso l'andamento in AR è molto più linerare e le correzioni software sono decisamente migliorate.
Anche il grafico della DEC è migliorato perchè sono praticamente scomparsi gli errori di guida dovuti al backlash.
_________
In 2010 I bought a used skywatcher HEQ5Pro. It was practically new and used very little.
During the first use I realized that something was not working well during the guider (sometimes frames showed the stars elongated already with focal 560mm court). I then did some tests to try to understand and solve the problem. I used to test the SC C8 reflector reduced to 1650mm focal length and MagZero MZ5m.
Well looking at the AR graph with autoguiding enabled and disabled I realized that the problem was not software but was due to the mount.
In fact, with autoguiding disabled graph presented oscillations in AR with maximum-minimum continuous + 3-4 / -3-4 pixels that occurred every 13-14 sec. Any autoguiding software enabled tried to compensate for these errors but the correction is often added up the oscillations causing even worse errors. Setting correction times same or less than 1 sec, the result was a little better.
Someone advised me to revise the frame: dismantling cleaning, re-greasing etc. After that laborious effort the problem remained.
Then I noticed in watching the moving gears that the error is repeated each time a tooth the crankshaft gear entered between two teeth of the central floating gear.
I tried in every possible way to reduce these errors by adjusting the mutual distances of the three gears, but the result was almost equal.
The possible solution could be to replace the gears with belts; in the meantime I used main telescope with focal less than 500mm in order not to blur in long-exposure.
Several companies realize the modification kit with belts, but often the modification entailed the loss the gearing ratio of the original setup making unusable the handset in the HEQ5. The only way to handle the mount would be to use the EQMOD.
A few months ago I learned that the company Rowan Astronomy (UK) realized the HEQ5 Pro Belt Modification Kit (www.rowanastronomy.com/productsa1.htm) that maintains the gearing ratio of the original setup .
So I bought the kit. The change was very simple, and in a short time.
I refer you to the album Facebook www.facebook.com/media/set/?set=a.1199861523390411.107374... where you will find more details and tricks.
The first thing you notice is the drastic reduction of the metal noise during the go-to.
www.youtube.com/watch?v=r5bu97zoRok,
The graphs before-after are eloquent. Now the shape of the curve AR is much more linear and software fixes have definitely improved.
The DEC's graph also improved, because virtually disappeared driving errors caused by backlash.

The moon is beautiful and marvelous to behold. With my telescope, I think I now enjoy it the most when it is a small sliver and has more dramatic shadows, but... there's something captivating about when we get a chance to view the whole side at once.
